As many already know, studying for the physics GRE and getting accepted into a graduate program is not the final hurdle in your physics career.

There are many issues current physics graduate students face such as studying for their qualifier, deciding upon a field of research, choosing an advisor, being an effective teaching assistant, trying to have a social life, navigating department politics, dealing with stress, utilizing financial aid, etc.

Mentioning them can only hurt my chances, since I'm also applying for all of these this cycle, but I'd want someone to do the same for me.

I would recommend applying for DoE CSGF, NDSEG, and Ford. HEP-ex is well within the supported fields for all of them, and they're great opportunities. With the exception of Ford (due 20th November), these aren't due for a while so you have time to think about them and work on your proposal. Other than these, I'm not aware of any others (besides the Hertz, whose deadline already passed and is more geared towards applied physics).
